Rotating, swivel, vise

[Klinton994]

I’m considering the purchase of a rotating, swivel, vise for home use. I was shopping on Amazon where I viewed a demonstration video. In the video there was a piece of material clamped in the vise jaws. To rotate the vise head 180 degrees the demonstrator had to first take pressure off the vise jaws before before loosening the hold downs that prevent the vise from rotating.
My first thought is that loosening the pressure on the jaws/material may allow your material to slip. Do all swivel, rotating, vises, operate this way? Is there a vise that allows the head to rotate without taking pressure off the jaws?

Thanks

Those vises are great for learning how to cuss!

There are some.. they have plungers to hold the rotation.

Believe it or not the one where you loosen up the jaw a tad work really well.. they are the better design. There are good examples.. typically older Asian, and then there are the new offerings which are not near as good.

The newer versions of these vises don't always have a separate rotation lock. The older Yost had two locks, and a third locking handle on the rotating area, not just the main screw, or the swivel base.

Might be this pin on the back


Seems to be a thing of the past.

Best rotator vise is the Swindens then comes the Chas Parker

Thanks for the replies. When rotating the jaw position and locking it in place, is the vise secured by a screw type hold down, such as what is used to secure the swivel on the base, or by a pin? I would like to be able to rotate the jaws accurately to 180 deg.

I had one of these. I was forever pinching my fingers between the handle and the dynamic jaw so I got rid of it. There was no space there.

I don't think Yost is that way.

 

[Klinton994]

I think you are correct. I did see one on Amazon, not a Yost, that had a degree dial indicator on the vise for rotating to a certain degree. I’ve reached out to the seller to see what sort of locking mechanism they use.

I've seen that style of vise that had a spring loaded pin that locks the vise in different (rotational ) positions. When looking at vises I didn't care for the jaws needing to be loosened to rotate it.

The new offerings are not good.. typical asian quality.

The old ones.. 20+ years old are made well.. very heavy.

I believe the Yost 750DI and other vises based on the Sawyer NuType design are designed so that tightening the vise, also tightens the rotating jaws in position, using the clamping pressure from the vise screw.
The pin may fix the jaws in position, but the jaws are only held firmly once pressure is applied.
This video showing the Harbor Freight Doyle vise that’s similar to the Yost 760DI, demonstrated this, starting around 1:30 in.

Swindens vises, have the clamping for the vise, and the clamping for the rotation, as completely separate elements, as can be seen in the videos on the Swindens website.

The Swindens vises supposedly cost a fortune though.

I’ve ordered the Yost 750-DI. Reading the Amazon reviews on the different rotating vises it appears they’re all made in China, and of questionable quality. I’ll know in a few days.
I appreciate everyones comments.

Not all rotating vises are made in China, but the ones that aren’t are expensive, and not as full features in various ways.
The 750DI design is mostly the sane as the original NuTupe vise, and there is a reason that is the design that was mostly copied, and it wasn’t because the design was simply.

A fortune in deed. About $2500 plus shipping for the 4in another $550 if you want the rotating base

There’s also the Bison Bial version, but that only has one jaw set, unlike the NuType version.

I'd buy a Yost and be done with it.
